I'm using an ATmega328 for a projekt and was wondering if I need to use a resistor for the input voltage? Thanks, Sofus Christensen

Ice for the competition is collected form gravel pits around Fairbanks. In the summer gravel is mined from old river channels. The resulting ponds contain little organic material. Additionally during nine month winter, temperatures range from +40 to -60F (+5 to -50C). These factors combine to create exceptionally thick clear ice. The following are pictures of an iced over gravel pit.

i watched a 3 minute clip on utube where a glass of water was pplaced on a table. next...salt was sprinkled into the water. then a straw was lit, placed into the water and removed after a few seconds. the water turned into ice. is this a camera trick or true

If someone froze trailer tail lights in an ice wall... turned them on...

If I ask you for melted ice and you come back the next day with plain water have you behaved unethically?

I want to make instant ice by mixing water and some chemical to produce ice instantly, i won't use it for drinking, just for cooling off this summer, which chemical will help me do that.? thanks any help is appreciated.

I need some dry ice. Does anyone know where to get it?

Hey everybody, I have a bunch of ICs lying around, about 50 of them, and I have no clue what any of them do. I've googled a few of them, without great results... What I'm wondering is: Does a website exist that has just a bunch of datasheets on ICs? AND, when I search for them, what item number do I use? Most have a 2 different strings, one with 5 characters and the other with more... Thanks!

I recently came up with the brilliant idea (read: scheme) of constructing gloves with built in  RGB LEDs that fade through colors randomly. I plan to sell these to ravers as they are usually spoiled rich kids (no offense) and I can fund my new found interest in electronics. My question is if anyone knows of any ICs that can control this without having to program it, like the LM3914 can work as a VU meter. If no such thing exists, then the cheapest alternative.

I have puled two components out of an old radio/amp/ cd player etc. and i want to know what they are and if i can use them to make an audio amplifier. one says BC Power Module  SVI 3101 D on the front and 424  1w2  on the back and has 14 legs (it can be seen here, this is actually the exact one i have from the same appliance :  http://farm2.static.flickr.com/1042/4733036801_a2d72f1df9.jpg ) . The other looks kind of like an op amp, it has 12 pins and the part no 5a3920, and below that 218 130a (as you can tell i am not a good at desoldering and not having a solder suck doesn't help).

I was thinking that what will happen if we arrange inlet & exhaust valves on the piston (spark plug remaining on cylinder head)? i think that may be by using metal foam on the cylinder head the knocking of the engine might decrease. please assume that somehow i use proper mechanisms for valve timing & they dont have any appreciable effect on the piston. just consider that the weight of the valves is added to the piston. i was wondering that this might increase the efficiency of the engine because suction will take place more slowly (so it will near a reversible process, so efficiency will increase) & force of the explosion will be better. please you ppl; if anybody can give me satisfactorily explanatory answers, do reply! :)

I live in a place where the temperature climbs over 95 degrees a day.  So I was wondering if anybody has any ideas of stuff that I can make with ice.  Thanks!

The World Ice Art Championships are held in the Ice Park in Fairbanks, Alaska. In 2009 the venue may move to North Pole, Alaska. Each team is provided with a site on a looping trail through the park. The sites are surrounded by small black spruce are double as R.V. parking in the summer. In 1999 I rented chainsaws from the blue bus for the competition.

Tried hunting through the 'ables, and also hunted for it elsewhere. Has anyone done an Instructable on making a Solar Ice Maker? And if not, will anyone do it? I've got some ideas for trying to use it as part of a home cooling unit, but I don't know how to make it yet. Thus, modifying it seems kind of out of the question. Thanks for any help in advance.

Looking for anyone's practical experience here. I have made backyard rink last 3-4 yr, now upgrade to Nice Rink liner. Holding water never a problem, many in Northeast last yr had limited time due to warm winter. My rink is triangle shape with legs 20x30. Slope on one side  goes from 1" to 7" or so, average ice thickness is 3-4". Part of rink over brick patio block. Use wood 2x6-2x10 borders. Was thinking of putting hay/straw under liner in the deep sections to reduce volume/depth so I can freeze solid and not have water layer under the ice. Or do you think the trapped air (under liner) will warm and work against this. I would think enough straw would not fully compress and help reduce water level, but then interface between liner and actual ground will have a lot of air space. Got a few months to think on this, my season is late Dec-mid Feb.

What happens when you put dry ice in a micro wave? Im just wondering cause a local grocery store is now selling dry ice for Halloween effects (yes i know they cant sell to minors).Are the result any thing like this? (i dont think that microwave was turned on)

It's my take on the Ice King's crown. For the "gold" part, I first tried gluing plastic paint buckets together, but they were too thin. I ended up covering the outside of one bucket in Bondo and then cutting in the peaks with a jeweler's saw. For the jewels, I cut a positive mold for each one out of a scrap of cutting board, then pressed them into clay to make a negative mold. Then I mixed up some casting resin and red dye and cast the jewels. They were epoxied onto the crown before I locked them in with Bondo bezels. If I were to do it again, I would use a more acute conic shape and make the peaks taller. I might also use fiberglass-reinforced Bondo and try a different gold paint. If I'm real adventurous I'll cast the thing out of scrap aluminum.

How to connect IC L298n with Arduino ??

I was just wondering if there was any unusual cupcake icings I could make as my cupcakes are a bit boring- buttercream, 'water icing' etc. So if you have any ideas can you let me know! Thanks!

I am new at electronics and I would like to knew more about AVR, Arduino, IC and others microcontrollers, so could someone give me site about it or make instructable whit codes, programming boards and pins.

I m making a project for my college. I m finding somw difficulty in getting ICs of it. So ne of u know ne good company website from where i can get free samples of ICs. Plzz tell me . I m from INDIA.

I want to make a voice changer circuit but it seems that WIN8072 is not available in our country. please help!

I recently got some ic's from texas instruments and two of them came in bags that say: notice!! moisture sensitive parts. bake prior to vapor or ir soldering to reduce the chance of damage.What does this mean?

I would like to make a readout for my knob-controlled DC power supply so I don't always have to use the voltmeter with it.   Web search for "LSI DVM" did not produce useful results. What are some good ICs to use for something like that?

Hello, It's a bit stupid to ask (I think), but essential to me. From all schematic I readed over intructables I never saw anything or anybody that cared for that. If a IC have a maximum and minimum current to respect ie: 6mA to 10mA, do we even care? Do I need to limit the current somehow? As I said, every schematic I readed never added any resistor or talked about anything relate to limiting the current on the VCC for the integrated circuit. I'm currently building a device that use one 555 timer IC in astable and a few others IC and they are all connected in parralel to the power suply. Thanks

It it possible to use simple components, arranged properly, in order to replicate the use of a simple IC, such as the 555 or LM386? If so, where could I find diagrams of the internal electronics? Google has turned up nothing so far... Thanks!

I am trying to incorporate more ICs into my projects, but am having trouble figuring out how to choose themWhat I want to know:-How to know what voltage a "digital switch" (AKA mini transistor) triggers at-How to make the "digital switch" more like a mini, programmed potentiometer.-How to find the correct IC (search bar? filter? website?)-whatever else there is to know about them.Thanks!

Hey I got Atmel ICE basic, 6 pin wire and atmega1248. I try to sent  program code, but there comes error message. How I should connect  pins? http://www.atmel.com/Images/Atmel-42330-Atmel-ICE_UserGuide.pdf http://www.atmel.com/images/Atmel-8272-8-bit-AVR-microcontroller-ATmega164A_PA-324A_PA-644A_PA-1284_P_datasheet.pdf

Alright, so, i have this ic chip and want to do a project with it, but the problem is , i don't know what it does therefore i don't know what i can do with it. the writing on top of the chip says mc34063 and underneath it says 1110 please help me if you know what it does? i will put a picture on this thread. extra info: i salvageed it from a radio i believe

I've been reading quite a bit about hydrogen boosters for vehicle motors ( gas and diesel )on the internet. Seems like there's some debate about whether they are effective. They are a bit pricey. Does anyone know of any DIY plans to make such a booster?

I have come to the instructables forum today in search for knowledge. So I have been working on a simple speaker system for my ipod shuffle, the speaker I used is quite old, but was the only one I found laying around. When I plug my ipod into the circuit everything works fine the only problem is that it is barely audible. Is there a way to amplify the sound so I can actually hear it without having to stick my ear right next to it? Pictures of my work so far will be provided. Oh also identifying the IC's included in the gallery would be of utmost help. Thanks in advance.

I have followed your instructions in https://www.instructables.com/id/SNF-Drumming-MIDI-Glove-using-Arduino-and-light-se/ and I successfully. I now make the same project but with 11 light sensors use arduino uno rev 3 and 4051 IC. Please help me to modify the original code to work with arduino uno rev 3 and 4051 ICs. Thank you very much link about arduino and 4051 1. http://playground.arduino.cc/Learning/4051 2. http://miscellanea.com/how-to-get-more-arduino-analog-inputs/ 3. http://dawson-station.blogspot.com.br/2010/01/mux-demux-cd4051-parlor-tricks.html

I have to make a project at the university and I would like to know whether IC LM 3915 is analog or digital? I'd also like to know the difference between the two types of IC's.

I need to know how to freeze water outside a freezer.

I have a little bit of dry ice and I can't think of what to do with it.I have alreadythrown it into the poolmade bubbles with itpointed my laser into itfroze a quarter in ita bunch of other things that I cannot rememberAny Ideas? I have an hour left with itNO DRY ICE BOMBSthey are illegal you know

Michael Natkin writes a culinary blog Herbivoracious which includes hundreds of recipes for a vegetarian diet. This, however, is an experiment using dry ice to create beautiful clouds of smoke while filling your home with sweet scents.

Where can I get dry ice?

What I was wondering is if, you could have a sled that could make ice to sled on. This can be divided into multiple questions. 1. Is it possible to have a tank of nitrogen and water in front of a sled, so that it combines nitrogen and water in a mist to create a thin layer of ice in front of the sled? Would there be any major changes to make it plausible? 2. Is there another way to make a thin layer of ice? 3. OR does this whole idea deserve the trashcan? I'm trying to put our heads together for ideas, by posting this question..... So try to look for possible solutions. Thanks, Paul

How to get 16 outputs from a mt8870 dtmf decoder ic  will this circuit works ?

What is the LM1778N IC and is there an alternative to it? Need two for this circuit: http://www.zen22142.zen.co.uk/Circuits/Audio/quad.htm Can't find anything about it online. Thanks, Edwin

I want to built my own orbot but dont know to programm the micro controller. in which language it can be done? is micro controller ic and micro pc ic are same?

When will the ICS update be available for  motorola xoom 2 in the UK? i mean...Jellybean is already out and im stuck with honeycomb! Motorola says it will be in the Q3...What does that mean?

I am looking for a chip just like the ones used in any calculator that does multiplication addition and subtraction. THe device i am looking to build has to be as thin as a credit card have a 8 character segment lcd and only be able to do addition and subtraction. so i need to be able to have buttons" 1 to 0 + - and = and . "nothing more. i looked at some attiny ics but they require a another ic to drive the lcd. also the the data entered need to stay in if the power of the ic goes out. most calculators have only one ic, any idea what the best ic for this application will be? thank you in advance. i need something this small. http://www.logopremiums.com/calculator-ballpoint-pen-HWK922LP.jpg Thank you

Hi I want to make a 4 relay controller with ir . That means I want to control 4 relays with ir based remote control I have see some modules from internet but the ic name is removed. I want a Ic ( not micro controller or maybe a Attiny 85) to read different signals from ir receiver and trun on and of the relays. So please give me circuit with ic name. Thanks   

SO i made a circuit which is a binary adder(using the 4008b) that adds numbers in binary and then passes on the result to a 4511 IC(its a BCD to 7 segment decoder),so basically it adds numbers in binary and displays them in decimal .It seemed to work fine for a while but then suddenly when i tried adding 0011 +0001(3+1) in binary ,it still displayed 0 and then i tried tapping the battery for a second or two and then suddenly the seven segment display shows 4 .The circuitry is all fine and right .but do i have to connect latch enable(pin 5) pin of the Ic?.Both the IC's run on a 9v battery and for the 4511 decoder IC i used 33k pull down resistor .Is my pull down resistor value for the 4511 IC too high ?The binary adder part seems to work very well,its the bcd to 7 segment decoder IC part that I'm very much concerned about.Is there too less power for both the chips to run on?I've not got a single idea at all .so, >PLS help me if you can.

Help me light some LEDs with an IC. Is there a simple 10-stage counter IC, just like the 4017, but where the outputs stay high until the chip resets. So the output would be as following: 1000000000 1100000000 1110000000 1111000000 1111100000 1111110000 1111111000 1111111100 1111111110 1111111111 and then repeat I'm building a circuit where the number of lit LEDs constantly increase. Do you know of a chip that can do this? Or can it only be achieved with a PIC? Thanks in advance Martin
